TO ALL WHOM IT MAY CONGERN:

Be it known that I, THOMAS Kenn, ot' York, in the county of York, Stateof-Pennsylvania, have invented a new Fanning Rocking Arm-Chair; and I doherebyr declare that thefollowing is a full and exact descriptionthereof, reference being had to the accompanying drawings, end to theletters of referencemarkd thereon.

` The nature of my invention ,consists in attaching a revolving fan,with a transverse rotary motion, to ordinary rocking-chairs, by which acurrent of air is produced without any other power than that used by theoccupant of the chair while rocking himself.

-To enable othersl skilled in the art tomake and use my invention,` Iwill proceed to describe its construction and operation.

Figure 1, in the accompanying drawings, represents the chair with theentire machinery attached, except the fan, which is represented in iig.3.

Figure 2 represents a side view of the chair with my invention attached,except the fan as represented in iig. 3.

Figure 3 represents the fan and pulley, to which the band or strap isattached, to communicate motion to the fan. A v Y i I I I I, in g. 1,represent the rockers of the chair, resting on a platformconsisting offour piecesframed together, about one inch in thickness, and from threeto four inches broad, and represented in fig.`1 by A A AA.

n n n n, in iig. 1, represent short pins, inserted in the sides ofplatform A A A A, projecting above said platform from a quarter to halfan inch, which pins, when the chair is in motion, are received intocorrespouding 'holes in the rockers ofthe chair, and thus kept firmly enthe platform.

O O,- in iig. 1, represent an upright board or plank, firmly attached toplatform A Al A A, L L representing a stripattached to the platform, inorder to throw O O further from the side of the chair.

B B, in fig. 1, represent a lever, with a cross-piece marked C G, andattached to the upright, O O, by a pivot, M. n

4H H, in fig. 1, represent two straps, attached to the Vright-handrocker at I I, and fastened to the lever B B at C.

F'F, in iig. 1, represent a strap, fastened to the extreme ends ofthecross-piece C C, and wrapped around the pulley E E, in g. I, representthe posts on which the fan and pulley rest.

P P P P, in fig. I, represent the back, arms, and seat of the chair.

Fig. 3 represents the fan, and a front view of the pulley.

C C, the shaft to which the several fans are attached.

l) D, the posts ou which .the fan rests.

The occupant ofthe chair, by rocking himself, imparts the motion to 'thefan. It requires very little additional power to that necessary to enjoythat luxury when this invention is not attached. i

The straps H H are alternately drawn forward and back by the rocker, tothe ends of which they are attached, which imparts a correspondingmotion to the lever .B B at Ci. This lever, having M as a centre orfulcrurn,'which 1s stationary, being attached to a platform by theupright, O O, has a corresponding forward and backward motion at thetop, and the strapF F, being fastened to either end of the crosspiece CC, and wrapped several times around the pulley D, attached tothe shaftof the fan, imparts a transverse rotary motion to the fan.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the platform A A A A, the projecting pins n n n, theupright, O O, with lever'B B. straps II H, strap F F, pulley B, shaft CC, and fan A A, as described.
